SEAL-PRESS.

SPECIFICATION forming part of Letters Patent No. 553,132, dated January 14, 1896.

Application filed arch 22, 1894:.

0 on whom it may concern.-

Be it known that I, ALBERT J. PAR-K, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and use ful Seal-Press, of which the following is a specification.

My invention relates to improvements in seals, such as are used by notaries public and others; and the object of my improvement is to provide a seal which shall be much lighter in weight and less cumbersome than the present well-known device that is operated by a lever. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a plan view of the seal; Fig. 2, a side elevation showing the two jaws open; Fig. 3, a side elevation showing the two jaws closed; Fig. 4, a plan view of the under side of the upper jaw on line 1 2, Fig. 2; and Fig. 5 is a side elevation of a modification which will be hereinafter described.

Referring to the drawings, A represents the upper jaw and B the lower jaw of the device, which are made of metal and pivoted together at one end by the transverse pin 0.

D is a vibrating transverse screw pivoted to the inside of the lower jaw B by means of the pin E, and passing through a transverse opening in the upper jaw A.

F is a thumb-nut fitted on screw D outside of the upper jaw, adapted to be turned against said upper jaw to draw the two jaws toward each other.

G is a spring passed around the pivot-pin O, and whose ends bear against the inner faces of the jaws to exert a constant outward pressure thereon to hold the same expand ed as far as the thumb-nut on the screw D will permit. As other spring devices may be used to ef feet a like result, (an instance of which is Serial'No. 504,686. CNo model.)

shown in Fig. 5,) I do not limit myself to the above-described spring passed around the pivot-pin O. In said Fig. 5 I have shown a spiral spring G interposed between the two jaws, which, as will be observed, effects the same result as by the first-described spring.

H II are two plates attached to or forming parts of the inner sides of the outer or free ends of the jaws A andB, the letters or device (seeFig. 4) on one of the plates being raised and the corresponding letters or device on the other jaw being depressed or sunk, so that one will fit into the other when the jaws are closed by turning the thumb-nut F, and thereby form the desired impression upon the paper, parchment, or other similar material I, placed between them.

Having described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

As an improved article of manufacture, a seal, consisting of the two jaws A, B, pivoted at one end by a pin 0, and having formed upon or secured to the inner sides of their outer ends, plates H, H; one plate being provided with the letters or device required to produce the desired impression, raised, and the other plate the same letters, or device, depressed, or sunk; in combination with a suitable spring for exerting a constant outward pressure on the jaws; the transverse, vibrating screw D, pivoted at one end to the inner side of one of the jaws, and passing out through the other jaw, and a thumb-nut F, fitted over the outer, free end of said screw, and adapted to be turned up against the outer side of the jaw, substantially as and for the purpose set forth.
